I've been on a pill for almost 2 years, and had used it before as well. Last week was a no-pill week but I didn't get my period. That has never happened before! No early signs of pregnancy, test negative. On Monday I was supposed to start a new pack of pills but I didn't.
So the question is do I wait for a month for my next period (which I will hopefully get) and resume the pill on the first day, or do I start taking it again now? Of course, I'm aware that I need additional protection one way or the other, my concern is more about throwing my hormones off if I decide to wait for my next period.
